In that fleeting instant when Pan Gu's figure opened his eyes and the Heaven-Opening Divine Axe in his hand struck the center of Shen Ni's brow-
Lin Tian extracted that fragment of Pan Gu slaying Shen Ni.
Then he merged that fragment into the four rivers of time, fate, power, and space.
Like a celestial maiden scattering flowers, he scattered that fragment of Pan Gu slaying Shen Ni with the Heaven-Opening Divine Axe into the different fragments of time and fate throughout Shen Ni's past, present, and future!
He used that fleeting instant of Pan Gu slaying Shen Ni to replace every scene and every process in which Shen Ni had appeared in the Primordial World!
And he made that single instant the entirety of Shen Ni's experiences, from the moment of his birth to the present!
In other words.
If Lin Tian could successfully replace all the countless years since Shen Ni's birth, it would be tantamount to killing Shen Ni in the very instant he was born!
And by fighting war with war, he would completely curb the corrosion and contamination that Shen Ni's Dao-unified origin was inflicting on Lin Tian's forty-nine origin laws.
Lin Tian acted without the slightest hesitation, never dragging his feet.
After all.
The situation now was even more perilous than when he had faced the Yin-Yang Mirror Demon God. His life hung by an even thinner thread.
At that moment.
Lin Tian's three species forms-
The Dutian Two-Principles Vine, his true Hongmeng Fierce Bird body, and his Yin-Yang Mirror Chaos God and Devil species form-all ascended simultaneously into the sky ten thousand miles above the Heavenly Passage River.
Drawing upon the threefold tribulation lightning of All-Heaven, the Great Dao, and the Heavenly Dao, they melded into an immensely grand species form.
